POROUS SOLID DRAINAGE MATERIAL WITH PARTICULATE PHASE BOUND BY HYBRID OPC-GEOPOLYMER PHASE

Abstract: an environmentally-friendly and sustainable porous solid surface-water drainage material with high recycled waste content and excellent water infiltration rate is provided. a first phase of recycled particulate materials is bound by a second hybrid geopolymer/opc phase to create a material having a porosity of 10-25 percent, a water filtration rate of at least 18,000 mm/hr, a 28-day compressive strength of at least 10 mpa, and a density of less than 1,850 kg/m. the porous solid surface-water drainage material may be used for high drainage regions such as solid surface storm drains and other infrastructures that permit passage of water while preventing access to standing water by mosquitoes and other insects, thereby preventing insect-borne disease transmission. the material can be dyed and shaped for a variety of infrastructure applications, resulting in improving road and pavement safety.
